No becuase although its niche car, the market will be still bigger and maintain the prices of those V6's for much longer than a barry'd up (over spec'd) corsa.
People have choices and I expect his spec is too personal (too high) so he'd need to find someone who wants a VXR in that colour with that exact spec and willing to pay that price to get a reasonable price otherwise people will say well I'll get a std one and feltle it how i want and save 3- 5k doing so.... unlike the Clio V6 market where you either afford to buy one or you cant.
I still maintain he's an idiot but if it isnt for people like this we wouldnt have the tuners we do to produce our much cheaper tuned hot hatches.
i wasnt specifically talking about 2nd hand value, just in general, the amount of money for such a (type of) car. I know V6's keep thier value pretty well, especially compared to a corsa (no matter how many 888 bits it has!)
like people have mentioned, for that cash you could have a whole heap of other things.
And for all we know,
he may keep it for 10 years or longer, where 2nd hand value is totally irrelivant!
